     1.4    Build shared companion libraries.
     1.5  
     1.6  --------------------------------
     1.7 +Symptoms:
     1.8 +  While building the final gcc, I get an error message that ends with:
     1.9 +    libtool.m4: error: problem compiling FC test program
    1.10 +
    1.11 +Explanations:
    1.12 +  The gc build procedure tries to run a Fortran test to see if it has a
    1.13 +  working native fortran compiler installed on the build machine, and it
    1.14 +  can't find one. A native Fortran compielr is needed (seems to be) to
    1.15 +  build the Fortran frontend of the cross-compiler.
    1.16 +  Even if you don't want to build the Fortran frontend, gcc tries to see
    1.17 +  if it has one, but fails. This is no problem, as the Fortran frontend
    1.18 +  will not be built. There is nothing to be worry about (unless you do
    1.19 +  want to build the Fortran frontend, of course).
    1.20 +
    1.21 +Fix:
    1.22 +  None so far. It's a spurious error, so there will probably never be
    1.23 +  a fix for this issue.
    1.24 +
    1.25 +Workaround:
    1.26 +  None needed, it's a spurious error.
